SPECIFICATION forming part of Letters Patent No. 768,804, dated August30, 1904.

Application filed October 16, 1903.

To all whom, it may concern;

Be it known thatI, RUTHERFORD H. HUTCH- INSON, a citizen of the UnitedStates, residing at Layton, in the county of Davis, State of Utah, haveinvented certain new and useful Improvements in Mowing-Machines; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it This invention relates to mowing-machines; and it hasfor its object to provide a machine wherein'two sets of knives will beslidably mounted upon a cutter-bar for cooperation in the place of theusual arrangement of a single knife and fingers and in which the kniveswill be reciprocated through the medium of a mechanism that is simple inconstruction while being positive and efficient in its operation.

In the drawings forming a portion of this specification, in which likenumerals of reference indicate similar parts in both views, Figure 1 is.a top plan View of a mower embodying the present invention. Fig. 2 is atop plan view of the cutter-bar employed with the two sets of knives.

Referring now to the drawings, there is shown a mower embodying acutter-bar 5, from which project forwardly the rods 6, which serve todivide the mass of material to be cut into sections and hold it againstlateral movement during the operation of the knives. Upon the bar 5 aremounted slidably the two sets of knives 7 and 8, these sets of knivesbeing held by suitable guides in such manner that they may beindependently reciprocated.

The frame of the mower includes the sleeve 9, in which is mounted theaxle 10, having a pair of ground-wheels 11 fixed at each end Serial No.177,296. (No model.)

' thereof and having also a gear-Wheel 12. The

sleeve 9 is provided with ears 13, in which is journaled a counter-shaft14, carrying a pinion 15, that meshes with the gear 12, and at one endof the counter-shaft is a crank-disk 16. A rocker 17 is pivoted to theframe by means of a pin 17 and includes an arm 18, which is connectedwith the crank-pin 19 on the disk 16 by means of the pitman 20, so thatas the machine progresses the rocker is oscillated. Rods 21' and 22 areconnected to the ends of the rocker 17 and to the series of knives 7 and8, respectively, and thus oscillation of the rocker causes reciprocationof the sets of knives oppositely.

With the present arrangementthe material ,to' be cut is positivelyengaged and there is a shear cut at both sides thereof.

'Whatis claimed is A mower comprising a frame having a plurality of carsprojecting therefrom, a shaft mounted in the frame, ground-wheelsconnected with its ends, a second shaft revolubly mounted in the ears,gears connecting the two shafts, a crank-disk carried by the secondshaft and having a pin, a rock-lever mounted upon the frame and havingarm-s projecting oppositely therefrom, a pair of knife-bars disposed one,upon the other, pitmen connecting the knife-bars with the arms of therock-lever, and a pitman connecting the free end of the lever with thepin of the crank-disk to move the lever upon the pivot when the saiddisk is revolved. I

In testimony whereof I aflix my signature in presence of two witnesses.
